Hi Steve, Thanks alot for the help and the code. I'm using the mica2 mote(and if i'm not wrong it uses the cc1000 chipcon for radio), so do you think it is compatible? as you probably know the interfaces are not the same at all bet. the cc2420 and cc1000, so i'm not so sure what i can do.
for you help i'll be grateful Itamar ----- Original Message ----- From: Steve McKown <[EMAIL PROTECTED]> Date: Monday, May 21, 2007 23:33 Subject: Re: [Tinyos-help] Allocating address to a mote using the ActiveMessageAddressC component To: [email protected] Cc: Itamar Amsili <[EMAIL PROTECTED]> > On Monday 21 May 2007 06:23, Itamar Amsili wrote: > > I need to allocate a new address to a new mote who joined the > network,> (or maybe change a mote's ID from 1 to 2). > > I want to do the allocation inside the program (dymanic), and > i think i > > need to use the ActiveMessageAddressC component. > > Do i need to use the ActiveMessageAddressC ? and how to use it? > > Can one shows me that? > > And if not using the ActiveMessageAddressC, what other options > do i have? > > I'm using ActiveMessageAddressC and it mostly works.
